Microstructure And Performance

Obvious physical process differences exist between overlapping area and non-overlapping area by broad-beam laser cladding,also the parallel and vertical interface of RP.By comparing the microstructure and performance, the result shows: the microstructure of overlapping area has broken crystal,the size of overlapping area crystal is bigger than the non-overlapping one.Repeated heating makes overlapping area secondary dissolving out and having higher rigidity;Between layer and layer of broad-beam laser cladding RP is metallurgical combination completely,the degree of uniformity of central microstructures performance is good,hardness of the bow shape area between overlapping layer and matrix is greatly increased.

ABSTRACTStructural and electrical characterization of laser recrystallized LPCVD silicon films on amorphous substrates using a shaped cw laser beam have been performed. In comparing the results to data obtained using a circular beam, it was found that a significant increase in grain size can be achieved and that the surface morphology of the shaped beam recrystallized material was much smoother. It was also found that whereas circular beam recrystallized material has a random grain structure, shaped beam material is highly oriented with a <100> texture. Finally the electrical characteristics of the recrystallized film were very good when measured in directions parallel to the grain boundaries.
